When you upgrade the application server to a newer version, be aware of the following settings that you might want to change.
The EJBDeploy tool was installed automatically with the product in WebSphere® Application Server Version 7 and earlier. It is now an optional feature.
The process for managing the centralized installation manager (CIM) for WebSphere Application Server Version 6.1.x and 7.x is different from the process for managing Version 8.0, and each process is documented separately in the information center. For Version 8.0, CIM uses the Installation Manager to install the product on remote machines. For Version 6.1.x and 7.x, CIM uses the ISMP and Update Installer.
Beginning with WebSphere Application Server Version 8, many of the job-submission functions of the job manager can also be performed by a deployment manager.
In WebSphere Application Server for z/OS® Version 7 and earlier, the Web server plug-in for IBM® HTTP Server (IHS/390) was located in the bin directory of the WebSphere Application Server for z/OS base product. In Version 8, both Web server plug-ins are in the bin directory of the Web Server Plug-ins product file system. Update any IHS/390 configurations to point to the new location for Version 8.
In WebSphere Application Server Version 8 and later, WorldType Fonts are not included with the product. If you require these fonts, change your applications to use newer fonts that are bundled with your operating system or obtain the Infoprint Fonts: WorldType Fonts for AFP Clients (Product 5648-E77).
